CORPORATIONOF MASSACHUSETTS] 7 HARNESS coan non {Loot/rs Application filed Septemberfl, 1331. Serial 1V9. 563,294.

This invention relates to an improved harness cord for looms, sometimes known as a dobby cord, and employed to connect the top of the harness with the harness lever.

The object of the invention is to provide a harness cord which will be strong and durable; and to attain this endthe invention contemplates the employment of an improved ferrule by means of which the flexible por ,tion of the cord is secured to a suitable screw device which may have either a hook or an eye embodied therein.

The invention consists in a harness cord for looms as set forth in the following specification and particularly aspointed out in the claims thereof.

Referring to the drawing Fig. 1 represents a front elevation of' harness cord embodying our invention, the central portion of the cord being broken away to save space in the drawing. o

Fig. 2 represents an enlarged sectional elevation of one end portion of the cord.

Like numerals refer to like parts throughout the several views of the drawing.

In the drawing, 5 is a cord embodying therein a core 6, preferably consisting of a plurality of flexible wire strands. The core 6 is covered with a covering of textile material 7 which is preferably braided in a wellknown manner. Located at each end of the cord 5 is a ferrule 8 provided with a recess 9 projecting inwardly from one end thereof, into which the end portion of the cord is inserted with an end portion of the core 6 projecting a short distance beyond the extremity of the braided covering 7.

A passage 10 extends transversely through the ferrule 8 at an intermediate point thereof, and this passagelO communicates with the inner extremity of the recess9 through a passage 11, the center of which is coincidental with the longitudinal median line of the ferrule. A screw-threaded hole 12 is also pro vided in the opposite end portion of the ferrule from that upon which the recess 9 is located and also communicates with the transverse passage 10.

A screw device 13, which may have a hook embodied therein as illustrated at the right.

which is caused to adhere to the hand end of Fig. 1 or aneyeembodied therein illustrated at the left hand end of Fig. 1,.

is'provided with a screw-threaded portion 14 V which is located in the hole 12, and also has a tapered end 15' provided thereon which pro' jects into tlietransverse passage 10. The tapered portion 15 of the screw device 13 is provided for the purpose of engaging the end portions of the strands 6 and deflecting the same laterally,- asillustrated at 16, in the trans-verse passage 10'and thereby forcing certain of said strands against a shoulder 17 which is: formed at the intersection of the passages 10and 11. Afterthe end portions 16 of the strands have been deflected, a greater portion of the passage 10 is filled with a suitable; fusible .mat'erial 18-, preferably solder,

exposed portions of the strands 16', the wall of the passage 10 andthe inner extremityv of the screw device 13. The end portions 16 of: the strands 6' are therefore first securely clamped against the shoulder 1'! and then enclosed within a covering of fusible material in such a manner that it is impossible to pull thejcord 5 out of the ferrule, and it has been found that when excessive pressure is applied to the cord that it will break between the ferrules before itwill pull out of the same orb reak at the shoulder 17 At the same time the fusible material 18- will prevent the screw device 13 from rotating within the ferrule and thereby become loosened from the end portion of the core 6.

We claim: 1. A harness cord for looms embodying therein a core offlexible wire, a ferrule enclosing an end of said cord and provided with a transverse opening therein, said wire terminatmg 1n said opening, a screw device mounted'in said ferrule and engaging the end of the latter in the opening,

ferrule and embodying therein a tapered extremity, the latter engaging the end portions of the strands and deflecting the same laterally in the transverse passage. I Y

3. A harness cord for looms embodying therein a core of flexiblewire strands, a fer- 7 rule enclosing-an end of said cord and provided witha passage extending transversely therethrough, said wire terminating in said assage, a screw, device nioimted in'said ferrule and embodying thereina tapered extremity, thelatter engaging the end portions J of the strands and deflecting the same laterally in the transverse passage, and afu' sible material in the transverse passage and adher ing to the deflected portions of the strands 4;. A harness cord for looms embodying therein a core of flexible wire strands, a ferrule enclosingan endof said cord and provided with a longitudinal passage'therein in which the cord is located and with a transverse passage intersecting said longitudinal passage, said strands terminating in the transverse passage, and a screw device mounted in said ferrule and embodying therein a tapered extremity, the latter engaging the end portions of the strands and deflecting the same:

in the transverse passage. 1

5. A harness cord for looms embodying therein a core of'flexible wire strands,a ferrule enclosing an end of said cord and provided with a longitudinal passage therein in 7 which the 'cordis located and with a transverse passage intersecting said longitudinal passage, there being a shoulder providedat the intersection of sa1d passages, sa1d strand terminating in the'transverse passage, a screw device mounted in said "ferrule and embody-, 7

ing therein a tapered extremity, the latter engaging the strands and clamping the same against said shoulder and deflecting the end portions thereof laterally in the transverse passage, and a fusible material in the transverse passage and adhering to the exposed portion'of said passage, to the strands, and

to the screw device.

7 In testimony whereof we have hereunto set our hands.
